whereby the ventilator member is automatically .20

shifted in its position by the action of air current to secure the "most advantageous ventilation depending on the direction of the air current.

Another object ofmy invention is the provision of a'ventilator device having'novel support-- ing means for supporting'the'same in conjunction with a window frame, 'whichflsupporting meansare automatically adjustable for use with window frames of various sizes.

For the accomplishment of the'foregoingobjectives, I provide a window ventilatordevice in which the ventilator member maycomprise a paneof glass or Plexiglas, or the-like, and in which the supporting means for supporting the device in conjunction with awindow frame comprises spring pressed laterally extending supporting-arms, the outer ends of which are adapted to hook into or otherwise engage in the channel portions of a window "framewhich normally reber has pivotal or rotational association with the lateral supporting arms, whereby the ventilator member is mounted for pivotalor rotational movement in the plane of the ventilator memher. The supporting means for supporting the 45 Figure 1 'is a perspective view of a portionofa ao Figure 4 is a top plan view of the lower supporting "unit showing more particularly the mounting of the spring pressed lateral supporting arms, looking into the interior of the housing-containing the "spring, and Wibl'ith cover for said spring housing removed.

designated by the numeral t, for pivotal or rotational movement of the ventilator member 1 with respect to the supporting means comprising the supportingunitsz and 3; l

"The lower supporting unit; as seen best in Figures 2, 3 and-4, comprises the lateral supporting'arms 5 and 6, the outer ends of which are slightly curved or outwardly offset as shown so as to readily hook into or otherwise engage in the channel portions 4a of the window frame l, in which channel portions 4a the window 8 is received for slidingmovementof the window relative to the window frame. The lower supportingu-nit further comprises anchoring means for anchoring the inner ends of the supporting arms 5 and Gandfor applying a spring tension to said ceivethe window member. The ventilator memc40 arms tending to urge the said arms 5 and 5 outwardly or away from one another toward 'the sides of the window irame 4,- and the lower supporting unit also 'comprises a holding member for holding the ventilator member, which holding member is pivotally associated with the anchoring means for pivotal movement of the holder relative thereto.

The anchorin means comprises a cup-shaped housing 9, in the bottom of which is an aperture through which extends the reduced end Illa of a shaft II] which is held in position as shown in Figure 3, by means of a snap ring H which fits into a circumferential groove in the reduced portion Illa of the shaft just above the bottom of the casing or housing 9. The side wall of ber or other resilient engaging member Ventilator device.

the housing 9 is cut away as indicated at 9a so as to permit the inner ends of the supporting arms and 6 to extend through the cut out portion of the housing 9 into the interior thereof and the inner ends of the arms 5 and 6 are bent to hook-shape for pivotal connection with the reduced portion IIla of the shaft I0.

Within the housing 9 is mounted a coil spring I2, the opposite ends I2a and I2b of which are respectively engaged with the arms 5 and 6 so as to press the same and urge said arms outwardly away from one another, the limits of the outward movement of the arms 5 and ti gagement of said arms with the edge of the wall of the housing9 as shown best in Figures 3 and 4. The housing 9 is provided with a cover I3 which may be suitably secured to the housing 9 as by crimping the circumferential edge of the cover I3 over the flanged upper edge of the housing 9.

The holding member I4 for holding the ventilator member is pivotally secured to the cover member I3 of the housing 9 for pivotal rotational movement of the holding member I4 relative to the'housing 9. This ventilator holding member I I is in the form of a U-shaped channel clamp adapted to receive within the channel between its sides a portion of the pane of Plexiglas or like material forming the ventilator member I, the channel clamp or ventilator holding member I4 bein provided with a set screw I5 adjustably engageable with the ventilator member I for retaining the same in position within the holding member I4. Portions of the sides of the holding member I4 are struck downwardly as indicated at I la and Nb in Figures 1 and 3 particularly so as to provide a supporting base or bearing for the holding member I4 on the cover I3 of the housing 9, the holding member I4 being pivotally secured to the housing 9 by means of a pivot pin I6 passing through the cover member I3 and the bottom of the channel of the holdin member I4, and having one end upset beneath the cover I3 and the other end of the pivot member I6 upset above the bottom of the channel of the holding member [4.

The lower supporting unit 3 is provided with an adjustable arm I! which is adjustably received in an angularly disposed passage I0b extending through the shaft member In at an angle to the axis thereof. A clamping screw I8 is threadedly associated with the shaft member II], and the inner end of the clamping screw is adapted to engage a portion of the arm I3 received in the angular passage IIlb.

Arm I1 is adjustable to difierent fixed positions relative to the shaft I0 and maintained in adjusted position by means of the set screw I8. One end of the arm I1 is provided with a rub- I9 adapted to engage the wall of the building adja cent the window frame in which the window .ventilator device is installed.

The uppfir-supporting unit 2 of the window ventilator device is substantially the same as the lower supporting unit 3, except that the upper supporting unit 2 is disposed in inverted position and that it does not utilize any manually adjustable arm corresponding to the arm I! of the lower unit for vertical support of the window The parts of the upper supporting unit corresponding to parts of the lower supporting unit are designated by corresponding numerals bearing a prime designation; The

supporting arms 5' and 6, the outer ends of which are laterally offset outwardly so as to hool; into or otherwise engage in the side channels 4a. of the window frame 4, as previously described. The inner ends of the arms 5' and 6' are anchored in a manner similar to the corresponding arms of the lower supporting unit for pivotal connection to a shaft Ill secured to the housing 9 within which is housed a spring similar to spring I2 of the lower supporting unit similarly engaging the arms 5 and 6 to tension the same for urging them outwardly toward the opposite side of the window frame. The

' window ventilator holder I4 of the upper supporting unit 2 is pivotally connected to the housing 9' in a manner similar to the pivotal connection of the holding member in the lower supporting unit and is adapted to engage and hold the upper edge of the ventilator member I.

The ventilator holding members I4 and I4 are each provided with a respective rubber or other resilient bumper member 20 and 20'. which act as stop members to limit the pivotal or rotational movement of the ventilator member I by engagement of the stop members 20 and .26 with the lateral supporting arms 5, 6, 5' and 6.

From the foregoing it will be seen that the window ventilator device of my invention may be readily installed in conjunction with window frames of standard types of various sizes without the use of special fastening means or special tools. For this purpose, the ventilator member I having been clamped in the channel holding members I4 and I4 with the respective lateral supporting arms disposed as shown in Figure 1, it is only necessary to manipulate the arms 5 and 6 toward one another against the spring action and to manipulate the'arms 5 and 6' toward one another against spring action, while inserting the respective outer ends of said arms in the side channels 40. of the window frame 4, and to thereupon adjust the relatively movable arm I1 for the desired vertical supportin engagement of the resilient end portion I9 of said arm with the wall of a building below the window frame 4 in conjunction with which the ventilator device is installed. a f

. In practice, thelwindow ventilator device of the invention may be installed sot'hat'the ventilator member I extends outside of the window frame, or. outwardly of the building, as shown in Figure 1, or it may be installed so that the ventilator member I extends inside the building inwardly of the window frame, as desired. j In operation, the device, when installed, permits the pivotal or rotational movement of the facilitate the automatic rotational positioning of the ventilator member I by the action of'air current, the said ventilator member I is -preferably positioned in the holding members I4 and I4 so that a major area of the ventilator. member I is positioned at one side or the other of the pivotal axes of said holding members as shown in Figure 1, whereby;theventilatoljmember I tends to respond to the action. of air currents in the manner of;a weathervvane to position the plane of the member I, substantiallyparallel .to the direction of the incqm ngqair currents.
